Followup-For: Bug #897

Dear Maintainer,

*** Reporter, please consider answering these questions, where appropriate ***

   * What led up to the situation?
   * What exactly did you do (or not do) that was effective (or
     ineffective)?

dmesg|more 

also results in 100 percent cpu utilisation

dmesg|strace more

gives repeated output of the form:

poll([{fd=3, events=POLLIN|POLLERR|POLLHUP}, {fd=0, events=POLLIN|POLLERR|POLLHUP}, {fd=2, events=POLLIN|POLLERR|POLLHUP}], 3, -1) = 1 ([{fd=0, revents=POLLIN}])

   * What was the outcome of this action?
   * What outcome did you expect instead?

*** End of the template - remove these template lines ***
